[Qemu-devel] compiling qemu on ubuntu under parallels

Okay I'm having another go at you folk.  Again, please feel free to  
shunt me off in the proper direction when I get annoying.

According to Andreas, intel macs can't compile the QEMU source as- 
is.  I'd need to use Q which only works because it has been patched  
to accommodate gcc-4.  I've tried this and it works.  A script  
applies a bunch of patches and the resulting Q app works properly.

But I am a little worried about working with a forked source tree.   
We are building instrumentation for computer security research that  
will sit on top of QEMU.  Thus, we'd like to have it as close and  
compatible as possible to the original QEMU source.

So ... I tried compiling QEMU on an Ubuntu install running under  
Parallels.  Yes, I know this sounds ridiculous.  In many ways, it is  
ridiculous.  But it should work,right?  Compiled fine, once I forced  
it to use gcc-3.3.  However, I was shocked when the resulting qemu  
executable didn't *run*.  It complains about being unable to  
initialize SDL.  So then I tried compiling and running the test  
programs provided with SDL (testalpha, e.g.).  These also compile  
fine but don't run, generating the same SDL initialization error.   
Very annoying.

What's up?  Has anyone tried this perverse trick of trying to run  
QEMU under parallels?  I think Parallels might use SDL somewhere  
under the curtain, but I'm not sure why this would mean user-space  
programs linked against libsdl would break.  Perhaps I need to send  
this email to the Parallels people.

On a similar note, has anyone tried to compile and run QEMU under  
VMWare on a mac?

Thanks for all the help.

-Tim

What exactly is the problem building a darwin x86 gcc-3.4? I have built 
a darwin gcc x86 cross-compiler on a ppc host, which seems to create 
sane-looking executables, but have no intel mac, so...

I tried using the gcc-3.3 that comes with Xcode 2.4.  I don't have  
Leopard and so cannot try Xcode 3.0.  It did not work on my intel  
mac.  Also tried downloading gcc-3.3 and recompiling with

configure --enable-languages=c --prefix=blah/blah
make bootstrap

This fails.

My (limited) web searches indicated that Apple no longer supports  
gcc-3.3.  Something to do with ABI.  I didn't delve.  If anyone has  
succeeded in compiling and running qemu on intel mac with either the  
gcc-3.3 that comes with it or with a gcc-3.3 they themselves  
compiled, I'd love to hear about it.

Fails how? I think this is what Heikki was asking about. What were the
errors? It would be also curious to see what SDL errors Ubuntu gave. A
report like "This fails." is completely useless.

[Tim Leek]

Sorry.  Here's more info.

1. SDL's test programs fail running on Ubuntu running under parallels  
as follows.

% test/testalpha
Couldn't initialize SDL: No available video device

2.  Whereas the same test program runs fine on a real linux box  
running Ubuntu.  Displays a cute little smiley face that waxes and  
wanes.

3. gcc-3.3 won't compile under intel osx.  No I didn't try to tweak  
it or search extensively online to see if there are work-arounds.   
Possibly these exist. I have only copied the last 50-100 lines of  
output here.

% mkdir build
% mkdir install
% cd build

well, Apple's version of gcc 3.3 [1] works on Intel Macs -- at least  
for C programs. You might want to install it via MacPorts [2] or  
compile it manually (patches are here [3])
